Subject: 8xxx: Rename dma_xfer() to dmacpy()
X-Git-Tag: v2009.08-rc1~122^2~11
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=7892f619d40f4196e41e7114c5dfee9fad0f572f;p=u-boot

8xxx: Rename dma_xfer() to dmacpy()

Also update dmacpy()'s argument order to match memcpy's and use
phys_addr_t/phy_size_t for address/size arguments
